发明名称 SWITCHING POWER SOURCE CIRCUIT
摘要 PURPOSE:To hold a balance of both losses of transformers by connecting the transformers in parallel and series hybrid circuit, and preparing the same number of connections. CONSTITUTION:Resistors 10a, 10b, 10c, 10d represent the first loss of respective transformers, resistors 11a, 11b, 11c, 11d similarly represent the second loss of respective transformers, and a composite transformer 3''' is formed by two set of series and parallel connections. The total of the resistance values of the both losses becomes the same as the value of one transformer since the number of the parallel connections and the number of the series connections are the same two sets, and the balance of both is held. From this, the number of the parallel sets and the number of the series sets may be set to the same.
